Domain : set of all reals Range: set of all reals
(2x+3) / 5 Domain = All Real Numbers Range = All Real Numbers

it equals 13X.
The range depends on the domain and conversely.

The Range is all the Real numbers you can think of. The Domain is also all Reals.

Domain is the number of x values that can be used and not cause an imaginary result. Range is the number of the y values that result. In f(x)=2x-5 the range is all real numbers.
f(x)=2x+2. Put in 0, 1/2, 1, 3/2, 2... and you will get integer values. That is for the domain. The numbers you get when you put that in are the range integral values.
The domain of x^3 - 2x is whatever you choose it to be. That will then determine the range.
